The characters of the popular television show "Dinosaur Train" visited the National Mall Wednesday.
They were there to help the National Park Service kick off events throughout the country celebrating National Fossil Day.
The special day dedicated to dinosaurs is part of Earth Science Week, a program that encourages people, especially kids to study geosciences and the natural world.
A hunt for fossils was a major part of Wednesday’s program for kids. It also included discovering creatures that roamed Washington before people, children collecting sediments and recording their best dinosaur roar.
The event was topped off this by a visit from Buddy, the T-Rex and Buddy Bison from the National Parks Trust.
